Absolutely not! Viagra is a serious and potential dangerous medicine only for those who really need it., At 13 I imagine you have no problem being sexually interested and getting an erection. So you do not need it. You will not feel more pleasure using it if that is what you think. You get the erection but not a orgasm. Don't play with medicines.
Viagra is a prescription drug. It should only be given by a Doctor for treatment for Erectile Dysfunctions. It will be dangerous for persons to take it without a prescription.

A 13 year old doesn't need to take Viagra and may harm the new hormones that they are just starting to produce.
One word my friend ......no. Viagra is a prescription drug that should be prescibed by a Doctor. They will not give it to children.
Safe in what sense and for who and if young, why the Viagra? Use it when you don't need it and your body will become dependant on it.
It is not good for a 16 year old to use Viagra so you cannot be prescribed.

A 16 year old boy should not take any supplements. Just eat healthily and stay active.
